The long-awaited BOA closure model appears in BIOM HYBRID. In addition, it is equipped with GORE-TEX, which is waterproof, breathable, and windproof, protecting the player's feet from the various natural environments that golf faces. Yak leather is used for the upper. It is strong and lightweight and has excellent breathability and durability. The newly developed spike shape of ECCO TRI-FI-GRIP simultaneously fulfills the requirements of three different zones: stability, durability, and rotational support required for golf. Removable Ortholite inlay sole provides additional cushioning and breathability.
